a Professor at C.N. Yang Institute for Theoretical Physics, State University of New York, Stony Brook, Long Island, he's not content just to study the relationships between string theory and particle theory, but also to write goofy essays, and maintain this Web site.

This review gives an introduction into problems, concepts and techniques when quantizing matter fields near black holes. The first part focuses on quantum fields in general curved space-times. The second part is devoted to a detailed treatment of the Unruh effect in uniformly accelerated frames and the Hawking radiation of black holes.

A simple introduction into the renormalization group (RG) in quantum field theory and an overview of the renormalization group method. The third section is devoted to essential topics of the renorm-group use in the QFT.
